While decreased physical activity and increased sedentary behaviours are incriminated for their role in the progression of obesity, active video games (AVG) may offer a new alternative to increase energy expenditure in youth. This study is the first to examine the effect of a 1-h AVG play on lean and obese adolescents' energy expenditure.
Body composition and aerobic fitness were assessed in 19 obese and 12 lean adolescent boys (12-15 years old). Participants performed a 1-h AVG session (Kinect Sports technology) while wearing a portable indirect calorimeter (K4b2) to assess their energy expenditure and heart rate.
Body weight (91.0 ± 9.5 vs. 58.5 ± 12.4 kg), body mass index (32.2 ± 3.1 vs. 20.3 ± 1.6 kg m(-2) ) and body fat (38.1 ± 2.7 vs. 13.4 ± 3.9%) were significantly higher in obese adolescents (P < 0.001). Absolute energy expenditure was significantly higher in obese (P < 0.05) but not when corrected for body composition. Maximal heart rate reached during AVG was significantly higher in lean adolescents (190 ± 25 vs. 183 ± 28 bpm, P < 0.05). Time spent between 3 and 6 METs (Metabolic Equivalent Task) was not different between groups but time spent above 6 METs was higher in lean adolescents (P < 0.05).
Although lean and obese adolescent boys experienced similar energy expenditure relative to their body size during a 1-h Kinect AVG session, lean adolescents spent more time in moderate-to-vigorous physical activity.
虽然身体活动减少和久坐行为增加被认为在肥胖进展中起作用，但主动式电子游戏（AVG）可能为增加青少年能量消耗提供一种新的选择。本研究首次考察了1小时主动式电子游戏对 lean 和肥胖青少年能量消耗的影响。
对19名肥胖和12名 lean 青少年男性（12 - 15岁）进行身体成分和有氧适能评估。参与者在佩戴便携式间接测热仪（K4b2）的情况下进行1小时的主动式电子游戏（Kinect Sports 技术），以评估他们的能量消耗和心率。
肥胖青少年的体重（91.0 ± 9.5 与 58.5 ± 12.4 kg）、体重指数（32.2 ± 3.1与20.3 ± 1.6 kg m(-2)）和体脂率（38.1 ± 2.7与13.4 ± 3.9%）显著更高（P < 0.001）。肥胖青少年的绝对能量消耗显著更高（P < 0.05），但校正身体成分后则不然。在主动式电子游戏期间达到的最大心率在 lean 青少年中显著更高（190 ± 25与183 ± 28 bpm，P < 0.05）。两组之间在3至6梅脱（代谢当量任务）之间花费的时间没有差异，但在6梅脱以上花费的时间在 lean 青少年中更高（P < 0.05）。
虽然在1小时的 Kinect 主动式电子游戏期间，lean 和肥胖青少年男性相对于他们的体型经历了相似的能量消耗，但 lean 青少年在中度至剧烈身体活动中花费的时间更多。
